"Penn State University announced Wednesday it had dismissed three of the most serious charges against one of its top climate researchers, Michael E. Mann, but would continue to probe if he violated academic standards of conduct in connection with 'Climate-gate,' a series of e-mail exchanges that came to light after hackers pirated the University of East Anglia's server.
The university, which described this next step as the 'investigatory stage,' said it was not evaluating 'the science of global climate change, a matter more appropriately left to the profession. The committee is charged with looking at the ethical behavior of the scientist and determining whether he violated professional standards in the course of his work.'
In November pirated e-mails from the University of East Anglia's Climatic Research Unit surfaced showing Mann had engaged in a series of exchanges with researchers including the unit's director at the time, Phil Jones, in which the scientists derided their critics and discussed how to keep their findings out of the peer-reviewed scientific literature."
